SPECIFICATION forming part of Letters latent No. 252,080, dated January 10, 1882. Application filed October 24, 1881. (Nomodeh) Patented in England January 27, 1880.

To allnhom "it may concern Be it known that I, Gnonen DALTON, a subject of the Queen ofGreat Britain, andresiding at Leeds,fin the county of York, England, have invented certain improvements in and connected with machinery or apparatus for crushing or reducing gold-quartz, ores, coprolites, cement, clinker, or other like substances to an impalpable powder,(forwhich Ihave obtained a patent in England, No. 365, dated 27th January, 1880,) of which the fol lowingis a specification.

My invention relates to machinery orapparatus for crushing gold-quartz, ores, coprolites, cement, clinker, or other like substances which require to be reduced to an impalpable powder; andit has for its, object rendering the said machine better adapted for being employed in the crushing orreducing of coprolites, cement, clinker, or other like sub: stances. y

In carrying out my invention in order to effect this object the oscillatingnor. movable jaw is pivoted to one arm of a double-armed lever or levers mounted upon a center or t'ul-. crumvin the framing, and the other arm of such lever orof each of such leversis jointed to a connecting-rod operated by. an eccentric camor cranknponthe actuating-shaft. An

crushingapparatus,

adjustable toggle or toggles is or areprovided for obtainingthe lateral thrust of the jaw, which, in conjunction with its downward motion, produces thecrushiugaction. By means of the arrangement and combination of the parts hereinbefore described the great crush ing strain is sustained by the toggle or toggles and by. the main frame ot'the machine, and not I combine with the crushing apparatus a siev ing apparatus and elevator,so that the per tions'ot' the material not sufficiently reduced may be separated fromthe fine portions and carried up, to be again passed through the The-details of arrangrmen t of thejvparts of the apparatus generally may be somewhat modified without departing from the principle of the invention or altering the character of the machine. t v

V I have shown in the accompanying drawings three types of the crushing apparatus, which a only differ from each other in the.relative location of certain of the parts, and two modificationssof the sieving and elevating apparatus, either of which, as desired, may be used in combination with any one of the three types of crushing apparatus.

Figure 1 represents a longitudinal vertical section of a crushing or reducing and sieving and elevating machine constructed and arranged according tomy said invention. In this type the crushing or reducing apparatus is adapted for operating upon material of a veryhard nature, and the sieving apparatus is arranged immediately beneath the crushing or reducing apparatus, andis combined witha chainor endless-band elevator.

Fig. 2 is a plan of the combined machine corresponding to Fig. 1. t

a combined machine of the second type, in which the crushing or reducing apparatus is more particularly adapted for operating upon softer material. or revolving sieving. and elevating apparatus is shown in combination with the crushing or reducing apparatus; but a sieving and elevating apparatus of the description shown in Figs. 1 and 2 may be employed insubstitution for the revolving apparatus in this second type of machine, and the revolving apparatus may be likewise substituted in the first type of machine for the sieving and elevating apparatus shown in Figs. 1 and 2. v

Figs. 4 and 5 are res 'iecti-vely an. elevation and section of the raft wheel or revolving sieving and elevating apparatus.

Fig. fi'represents a longitudinal section of a crushing or reducing apparatus of the third type, which is specially designed tor reducing very hard materials. to afine state of division. The sieving and elevatingapparatus is not shown in this figure, although intended to be used. Either of the two modifications shown in the other figures may be selected.

Referring to Figs. 1 and .2, the oscillatiugor movablejaw A is pivoted at its upper end, a, to one arm, I), of a double-armed lever, B, mounted upon a center or fulcrunnc, in. the framingO, andthe other arm, b,o1t' whichlever is jointed at b? to a connecting rod,- E,operated by an eccentric cam or crank,d, upon the actuating-shaft D. A downward motion is thus imparted to the oscillating or movable Fig. 3 represents a longitudinal section of In this example a raft-wheel.

jaw A, and the lateral thrust of the jaw (which, in conjunction with its downward motion, produces the crushing action) is communicated through the intervention of a toggle or toggles, F, the latter being in this type of machine arranged at the bottom of the jaw A, so as to take nearly the whole of the back-pressure.

The toggle-block e is adapted to guides c e in the frame, and may be caused to slide outward or inward in order to vary the angle of the toggle or toggles by the act of adjusting the transverse wedge f, and the throw of the jaw A can be thus varied as required, according to the degree of division of which the material under operation is to be reduced.

Below the jaws of the machineis placed the sieving apparatus G, carried by a pivoted bar, 9, and having a to-and-fro vibratory or shaking motion imparted to it through the intervention of a crank and connectingrod, h, from a revolving shaft, H. The sieving apparatus is provided with screens 2' t, of difi'erent mesh, the upper one, 1', having a coarse and the lower one, i, a fine mesh. The material which has been reduced to a sufficiently fine state of division passes through both screens, and may be delivered at 70 into any suitable receptacle, while the coarser portion of the material is conducted into the elevator I,and byitsbuckets Z carried up and discharged into the chute K, to be again passed through the. machine. The shaft H may be driven by a belt and pulleys,m, from the main shaft D, and mayin its turn drive the elevator I through the intervention of a belt and pulleys, a, one of such pulleys being fast on the upper shaft, n, of the elevator.

Fig.3 illustrates the second type of machine, and Figs.4 and 5 show in detail the raft-wheel or revolving, sieving, and elevating apparatus, which is represented as employed in combination with the crushing or reducing apparatus in this type of machine.

The crushing or reducing apparatus shown in Fig. 3 only differs from that hereinbefore described with reference to Figs. 1 and 2 in the followingfeatures,videlicetz The lever B is pivoted by its arm b to the lower end, a, of the movablejaw A, and the toggle or toggles F are arranged above. In this case, for convenience, the wedge f, by means of which the position of the toggle-block c is adjusted, is operated in a vertical direction, the block working between lateral guides in the frame.

The sieving or elevating apparatus (shown in detail in Figs. 4 and 5) consists ofthe wheel M, which is mounted on a center or axis, 0, carried by the frame ofthe machine, so as to be free to revolve thereon, and has rotary motion imparted to itby anyconvenient means such, for example, as by spur-gearing-the wheel M being shown provided on its outer periphcry with teeth m for this purpose. The wheel is formed with screens it, the inner one, i,

having a coarse mesh and the outer one, i, a fine mesh. The material which has been operated upon in the crushing or reducing appa ratus is discharged therefrom at k'into the wheel M, and thatportion of the material which has been sufficiently reduced passes direct through both screens of the revolving wheel, and is delivered into. any suitable receptacle, while the coarser portion of the material is carried up by the buckets l and discharged into the chute K, to be again passed through the machine. As before mentioned, I may substitute for the raffwheel in this type of machine a sieving and elevating apparatus of the description shown in Figs. 1 and 2; and the raff-wheel may, if desired, be employed in the first type of machine in substitution for the sieving and elevating apparatus shown in those figures.

The third type of machine is illustrated in Fig. 6. It differs fromthe second type only in the use of two toggles 'or sets of toggles, E,

which take the whole of the back-pressure. The sieving and elevating apparatus is not shown in this figure; but either of the two kinds hereinbefore described may be employed in combination with the crushing or reducing apparatus.

I claim as my invention-- 1. The combination, with the fixed and movable jaws and operating-shaft of a crusher or reducing apparatus, of a rigid lever fulcrumed in the machine-frame, means for connecting it with the movablejaw and shaft, as explained, for imparting an up-and-down movement from the latter to the former, toggle-blocks, and one or more toggles arranged between stationary toggle-blocks and said movablejaw, so as to cause the latter to approach the fixed jaw by the downward movement thereof, substantially as described.

2. The combination, with the movable jaw ing apparatus as shown, and an elevator arranged to lift and deliver between thejaws of IIO the crusher the material too large to pass through the sieving apparatus, substantially as described.

In testimony whereofI have signed my name to this specification in presence of two subscribing witnesses.

GEORGE DALTON.
